Answer
Shalom!
Thank you for your question.
A child born to a Jewish mother is Jewish, whether or not the mother was married to the father when she got pregnant.
Of course, if the mother was halachically married to a different man when she got pregnant the child would be illegitimate. However, it does not appear by your question that this is a concern.
It should be noted, however, that all relations outside of marriage are to forbidden according
to Torah law. The mitzva of “Be fruitful and multiply” is a mitzva that is
concurrent with the mitzva of marriage.
